Course Description:

This course discusses the fundamental principles behing the design and operation of Radar systems for different applications. It is intended to make the student understand the principles of Radar and its use in military and civilian environment and give them them familiarity with navigational aids available for navigation of aircrafts and ships.

AIMS:

  1. To derive and discuss the Range equation and the nature of detection.
  2. To apply doppler principle to radars and hence detect moving targets, cluster, also to understand tracking radars
  3. To refresh principles of antennas and propagation as related to radars, also study of transmitters and receivers.

Teaching and Learning Pattern

The teaching of students will be conducted through lectures, tutorials, short classroom exercises, case studies, group discussions among the students and projects aimed at solving real life problems. The lecture material will be availed to the students in advance to enable them have prior reading. Solving real life problems in each theme or a number of topics will enhance the students’ understanding of the problem based learning techniques.

 Assessment method

Assessment will be done through coursework which will include assignments, class room and take home tests, project work and presentations and a written examination. Course work will carry a total of 40% and written examination carries 60%. Coursework marks will be divided into; Assignments 5%, Tests 10% and Practical/project Work 25%.
